REVERSIBLE ROTARY-DISK PLOW.

SPECIFICATION forming part of Letters Patent No. 651,522, dated June 12, 1900.

Application filed October 2, 1899. Serial No. 732,359. (No model.)

To all whom tam/(Ly concern:

Be it known that we, WALTER ANDREW BLAIN and WILLIAM C. BELL, citizens of the United States, residing at Blackstocln'in the county of Chester and State of South Carolina, have invented certain new and useful Improvements in Reversible Rotary Disk Plows,of which the following is a specification.

Our invention is a reversible rotary-disk plow; and it consists in the novel construction and arrangement of its parts, as herein after set out in this specification and the claims thereunto attached.

In the accompanying drawings, Figure 1 is an elevation of our invention. Fig. 2 isa longitudinal sectional View of our invention.

team may be attached. The front end of a plow-beam is mounted on the top of the tongue in such a manner that the front end of it may be raised or lowered, and thus the disk plow may be sunk deep, trail in the ground, or may be raised entirely out of the ground. The front end of this beam is pivoted to the front axle, so thatsaid axle and its tongue may be to a limited extent freely turned to ,is the lower end of the loop 18, the upper part of the loop passing over the platform 7 the right or to the left. Extending downwardly from this plow-beam is a bearing in which is pivoted the plow-foot, and on this plow-foot is journaled a disk plow, which" freely rotates. Also to the foot is secured a yoke-shaped brace, and to each end of said brace is secured a disk-cleaner. Thisplowfoot is pivoted or j ournaled in its bearing, and it is connected to a lever, so that the plowfoot and disk may be turned either to the right or to the left. The trailer or guidewheel is journaled in a bifurcated bearing, so that it may also turn freely. The front end of this bearing is journaled in a cylindrical -so that the coupling may be better shown.

In Fig. 1 the right front wheel is left off,

1 represents the front axle; 2, one of the loops by which said axle is secured to the tongue; 3, one of the front wheels; 4, the tongue.

5 represents a strap or housing for the beam The platform 7 of this strap or housing is pro vided with rear and front perforations at the points indicated by the figures 8 and 9. The beam 10 has in its front end a vertical perforation at the point indicated by the figure 11, andin front of this perforation is avertical slot 12. (See Fig. 3.) Running through the perforations 8 and 11 is a bolt13, having two heads 14 and 15, the first above and the sec- "0nd below the platform 7. A pin 16 passes throughthe perforation 9 and the slot 12. Thus the tongue 4 and the axle 1 are allowed to turn to the right and to the left only to a limited degree, being arrested by the end walls of the slot 12 when the said axle is turned a certain distance either way.

Secured to the front end 17 of the beam 10 of the elevator 5. To this loop is pivoted the short arm of a bell-crank lever 19, the fulcrum-bolt 20 being pivoted to a bearing 21, secured to the upper face of the platform 17 of the elevator 5. end of said lever 19 forward or backward the Thus by moving the'free 5 front end of the plow-beam 10 may be raised or lowered to the extent of the distance be tween the upper face of the front end of said beam and the lower face of the shoulder 15. I00 Midway, the beam 10 is provided with a hollow bearing 22. This bearing may be integral with the beam or may be secured thereto in any substantial way. Below and impinging against the lower end of this hollow bearing 22 is a plow-foot 23, having a cylindrical rod 24 passing up through the hollow bearing 22, the upperend 25 of which, however, is square.

To the front face of the plowfoot 23 is pivoted a rotary plow-disk 26, and to the front face of the foot 23 and just behind the disk is secured an iron bar 27, terminating in arms 28, and to the front ends of these arms is secured a disk-cleaner 29. This diskcleaner consists of a sheet of metal, its lower edge nearly impinging against the front face of the plow'disk and keeping the same perfectly clean as it revolves.

To the square part 25 of the cylindrical rod 24 is secured a lever-arm 30, and to the free end of this lever is hinged one end of a pitman or connecting rod 31, (see Fig. 3,) the free end of which is pivoted to a lever 32. .This lever 32 is pivoted at the point 33 to a bearing 34, which is rigidly secured to the tail end of the hollow bearing 22. This tail end 35 of the hollow bearing extends back horizontally for some little distance and widens as it extends into a fantail, the extreme end of which is circular or curved, (see Fig. 3,) and running perpendicularly through the rear end of this fantail and concentric with a pivoted bolt 36 is a slot 37. From the pivoted bolt 36 and running underneath this fantail 35 is an arm 38, and above this fantail and from said bolt 36 runs another arm 39, and these two arms are rigidly secured to the said bolt 36, so that when said bolt turns to the right or left the two rear ends of these two arms also swing to the right or to the left.

To the lower end of the bolt 36 is rigidly secured one end of an arm 40, and to the outer end of this arm is pivoted the rear end of a lever 41, its front end 42 being pivoted to the lower end of the lever 32, so that when the upper end of the lever 32 is pushed forward the disk is turned to the left, the outer end of the arm is pushed back, which throws the rear ends of the upper and loworarms 38 and 39 to the left, the front end of the turning device 44 to the left, while its rear end inclines to the right. This movement throws the rear guide-wheel in such position as inclines it to run to the left, while it is, in fact, standing on a line with the beam 10. When the upper end of said lever 32 is pushed to the rear, it throws the disk to the right, the outer end of the arm 40 is pushed forward, which throws the rear ends of the upper and lower arms 38 and 39 to the right, the front end of the turning device 44 to the right, while its rear end inclines to the left. This movement throws the rear guide-wheel in such position as inclines it to run to the right, while it is, in fact, standing on a line with the beam 10. The rear ends of these arms 38 and 39 are each provided with vertical perforations 43.

Pivoted on the upper face of the upper arm arm 33.

39 is the turning device 44, having secured to its upper face and front end a'horseshoeshaped locking device 45. This turning device consists of a plate having a front circular end and having in its centeraperforation, a rear guide-piece 46, having its central part cut away, leaving a curved back part 47, and two side arms 48. Pivoted to the rear end of the fantail 35 is a spool 49, which works between the rear part 47 and the two side arms 48. Mounted and pivoted on the upper face of this turning device 44 is a cylindrical hearing 50, having a horizontal perforation passing through its center, and extending downwardly fromits body is a circular part 51, and attached to the rear part of this circular part is a shorter circular part or horseshoeshaped lock 52. Now when the rear end of the bifurcated bearing 53, in which works the guide-wheel 54, is turned to the right the two right-hand ends of these two horseshoe'shaped devices and 52 contact and keep the said wheel 54 from turning any farther to the right, and when the said bearing is turned to the left the left-hand ends of these horseshoe-shaped devices contact and keep said wheel from turning farther to the left. Thus it may be said that at a certain angle to the right the said bifurcated bearing is locked and at a certain angle to the left it is locked. The normal position of this wheel 54 is perpendicular, and there is attached to and extending from the front end and upper part of the cylindrical bearing 50 a segment-rack 55, and secured to the front of asquare part 56 of the bifurcated bearing 53 is an arm 57, having on it a locking device 58, the lower end of which sinks in the notches of the part 55, and thus the top part of the guide-wheel 54 may be inclined to the right or to the left.

tigidly secured to the lower part of the cylindrical bearing 50 is a bolt 43, which passes down through a perforation in the rear part of the arm 39, the slot in the fantail part 35, and the perforation in the lower On this bolt working in said slot is a spool 60 to prevent friction.

The rear end of the arm 38 is secured from falling out of its place by a nut 59.

The turning device 44, its rear end working over the spool 49, allows the bearing 53 to turn at right angles to the main body of the machine in order that the driver may make a short turn. Thus it will be seen that this plow is especially adapted to plow where we have to make quick turns either around hilly places or stumps or other obstruction and where we have to turn short at the ends of the rows and is particularly adapted to plow on the side of a hill, because by shifting the disk from one side to the other we can all the time throw the cut by going back and forth in the same cut, up the hill, or we may do the same on level ground, thus avoiding the necessity of having to lay the ground oflf in lands.
